An adult patient visits the clinic expressing concern about a lump that appeared on their neck about a week ago. Upon examination, the nurse finds a large, non-tender, hardened left subclavian lymph node without any overlying tissue inflammation. What could these findings indicate?

Choice A rationale A large, non-tender, hardened lymph node without overlying tissue inflammation could indicate malignancy. Lymph nodes may become enlarged or hard due to the presence of cancer cells. Choice B rationale While bacterial infections can cause lymph node enlargement, they typically also cause tenderness and overlying skin changes, such as redness or warmth. Choice C rationale Viral infections can cause generalized lymph node enlargement, but the nodes are usually tender and not hard. Choice D rationale Lymphangitis, or inflammation of the lymphatic channels, typically presents with red streaks on the skin, fever, and tenderness.
